How to find out how much traffic is transferred on the port?

Question

iptables

How to find out how much traffic is transferred on the port? Not the number of packets, but megabytes?

Answer 1

Add a rule at the very beginning:
Let's look at the counters:

[email protected]:~$ sudo iptables -L -v -n -x
Chain INPUT (policy DROP 0 packets, 0 bytes)
pkts      bytes target     prot opt in     out     source               destination         
   32     2554 ACCEPT     tcp  --  *      *       0.0.0.0/0            0.0.0.0/0            tcp dpt:8080

As you can see, 2554 bytes passed through port 8080.
